Microsoft’s Surface RT is just barely out, while the Pro is still not available, but rumours of next generation Surface products are already starting to trickle in.

According to a leak fresh out of Redmond, the company might looking to Qualcomm for its next-gen Surface RT, while AMD’s Temash quad-core APU could replace Intel’s Core i5 chips in the Surface Pro.

It doesn’t end there. The next generation RT is said to feature a smaller 8.9-inch form factor, while the Pro could grow to 11.6 inches, just to differentiate them a bit more. It sounds plausible, but there is talk of an even larger device in the works, a 14.6-inch Surface Book, a hybrid ultrabook with a proper keyboard and trackpad.

Needless to say, these early leaks should be taken with a grain of salt, although at least some of them sound plausible and frankly we would like to see AMD score a significant design win for Tamesh. It would spice things up a bit.

We got word that AMD is preparing to talk about a rather interesting processor around IDF 2012.

The Intel Developer Forum this year kits off on September 11 and AMD plans to snag a few journalists and show them parts like Trinity desktop parts and the rest of the Virgo platform, next generation Vishera AMD FX cores, but the new Hondo 40nm processor could be the most interesting part AMD has to show off.

Hondo was confirmed in AMD’s official roadmap a while ago and made an appearance back in February, at an official analyst day presentation. Hondo is a 40nm APU stuck at 4.5W TDP and one or two cores deepening on design.

It was said before that Hondo can run Windows 8 just fine and its purpose is to make affordable systems and run against Windows RT competition. Hondo is a first generation ultra-low power APU and it should get replaced by Tamesh, a second generation ultra-power part that should debut in 2013 at 28nm.

AMD is not seeking to contract more foundry suppliers despite the ongoing 28nm shortage. The company will stick with TSMC and Globalfoundries for its foundry needs, at least for the time being.

Taiwan Economics News is reporting that AMD is planning to move part of its 28nm production to Globalfoundries in 2013, but TSMC will still be retained as a contract supplier. TSMC will churn out next generation Sea Islands GPUs, while Glofo will produce Kaveri APUs. TSMC is also said to be on track to win contracts for Kabini and Temash APUs in 2013.

AMD is currently primarily focused on 28nm and 32nm products, namely Southern Islands GPUs and 32nm SOI chips like Trinity APUs. However, 40nm is still in play after AMD ditched plans for Krishna and Wichita. As a result, TSMC will continue churning out 40nm Brazos 2.0 parts until Jaguar-based designs such as Temash and Kabini go online sometime in 2013. TSMC will start producing tablet oriented 40nm Hondo APUs later this year.

In any case AMD is confident that TSMC and Globalfoundries will manage to handle demand in 2012 and 2013, which is hardly surprising given recent economic woes and weak channel demand.

AMD will shed more light on its upcoming Jaguar processors at the Hot Chips show in August.

Jaguar will be AMD’s first proper crack at the tablet market, although previous iterations of its low-power APUs tipped up in some designs a while back. In addition to tablets, the Jaguar architecture will also be used in low-power laptops next year, where it will replace current Bobcat parts.

AMD is not saying much about Jaguar ahead of the event, but analysts don’t believe this 28nm part will be revolutionary. Current generation Bobcat chips are considered too power hungry for tablets and even AMD’s upcoming Hondo tablet chip is still a 40nm part.

Jaguar could change all this thanks to its more advanced production process, but it will be an evolutionary design. Analyst Jim McGregor argues that AMD is continuing to evolve without reinventing the wheel. So, while little is known about Jaguar, not many people are expecting anything revolutionary.

AMD will also use the event to provide more details on its next-generation Steamroller CPU core, which should power AMD’s mainstream processors next year.

AMD is set to launch the first batch of Hondo APUs sometime in Q4. The launch should roughly coincide with Microsoft’s Windows 8 launch and we could see a few tablets based on the tiny APUs.

Hondo is based on the 40nm Bobcat core, of Brazos fame, and its power consumption is 4.5W. It packs DirectX 11 graphics and other features found in other Bobcat derived chips.

However, in 2013 AMD aims to replace Hondo with Tamesh, a next generation design based on the upcoming Jaguar core. There is still no word on the feature set or performance, but it is safe to assume that it will be major step forward over the venerable Bobcat.
